TECHNICAL FIELD

The present disclosure relates to a support connecting structure, a support, a baby crib, and a crib body of the baby crib.

BACKGROUND

Baby crib is a practical tool for placing babies. The conventional baby crib is generally manufactured by assembling solid woods into a fixed form. Customers buy the baby crib and place it in a fixed place at home. As the baby grows, more indoor space is required for activities of the babies. However, the conventional baby crib cannot meet requirements of folding and easy storage. Therefore, a foldable baby crib emerged. The foldable baby crib has the advantages such as easy assembly, disassembly, and storage, and therefore is favored by many customers. However, the disassembly and folding of the conventional foldable baby crib is complex and time-consuming.

FIG. 1 to FIG. 4 are schematic diagrams of a support connecting structure 200 according to an embodiment. The support connecting structure 200 includes a pivoting base 21, at least one arm 22, and a locking member 24. The pivoting arm 22 and the locking member 24 are mounted to the pivoting base 21. The support connecting structure 200 is applicable to, for example, a baby carrier. The baby carrier may be, for example, a baby crib (including a baby hammock, a baby playpen, and other types of baby cribs), a baby stroller, or the like. Rods of the baby carrier provided with the support connecting structure 200 can be unfolded and folded. Therefore, the baby carrier can be switched between a use state and a folded state to satisfy different use requirements of users.

In some embodiments, referring to FIG. 1 to FIG. 3, the support connecting structure 200 includes two pivoting arms 22, and the pivoting base 21 includes a pivoted connection portion 21 a. First ends 221 of the two pivoting arms 22 are respectively and pivotally connected to the pivoted connection portion 21 a by two first pin shafts 23. An axis X-X of each first pin shaft 23 is a pivot axis of the pivoting arm 22 corresponding to the first pin shaft 23. When the pivoting arm 22 is mounted to the pivoting base 21, a pivot axis Y-Y of the pivoted connection portion 21 a coincides with the axis X-X of the first pin shaft 23. In some embodiments, the first ends 221 of the two pivoting arms 22 are mated with the same locking member 24 located between the first ends 221. In some embodiments, a geometric structure of the pivoting base 21 may be, for example, symmetrical with respect to a median surface M-M between the two first pin shafts 23. The median surface M-M is parallel to the axis X-X of each first pin shaft 23 and perpendicular to a line connecting centers of the two first pin shafts 23. The first end 221 of each pivoting arm 22 includes a first anti-rotation surface 220. In some embodiments, the first end 221 of each pivoting arm 22 is formed by a plastic member sleeved on a rod-shaped member. In some other embodiments, each pivoting arm 22 may be an integrally formed member.

The locking member 24 is mounted to the pivoting base 21 and is capable of moving in a direction parallel to the axis X-X of the first pin shaft 23, therefore the locking member 24 can move to a locked position or an unlocked position. The locking member 24 includes second anti-rotation surfaces 240 that can be mated with the first anti-rotation surfaces 220 of the two pivoting arms 22, respectively. When the locking member 24 is moved to the locked position, the first anti-rotation surface 220 of each pivoting arm 22 can abut against one of the second anti-rotation surfaces 240 of the locking member 24, so as to prevent the pivoting arm 22 from rotating about the first pin shaft 23, such that relative positions of the pivoting arm 22 and the pivoting base 21 can be fixed. That is to say, the locking member 24 locks the pivoting arm 22 at a predetermined pivot position. When the locking member 24 is moved to the unlocked position, the first anti-rotation surface 220 is separated from the second anti-rotation surface 240, and the locking member 24 does not intervene in the rotation of the pivoting arm 22. That is to say, the locking member 24 releases locking of the pivoting arm 22 at the predetermined pivot position. As such, the pivoting arm 22 can rotate about the first pin shaft 23 to an appropriate position. In some other embodiments, the support connecting structure 200 may include one pivoting arm 22 and one locking member 24. Rotation or rest of the pivoting arm 22 relative to the pivoting base 21 is controlled by an axial moving of the locking member 24.

According to the support connecting structure 200 provided in the above embodiments, by changing the axial position of the locking member 24, the rotation of the pivoting arm 22 can be restrained or allowed. Therefore, the support connecting structure 200 having a simple structure and easily changed in state is provided.

Referring to FIG. 3 and FIG. 4, in some embodiments, the pivoting base 21 includes a slideway 210 slidably mated with the locking member 24. An extending direction of the slideway 210 is parallel to the axis X-X of the first pin shaft 23. In some embodiments, the locking member 24 may be non-rotatable relative to the slideway 210. That is to say, the rotation of the locking member 24 is limited by the slideway 210. As such, when the first anti-rotation surface 220 abuts against the second anti-rotation surface 240, the pivoting arm 22 does not push the locking member 24 to rotate. Many methods are available to implement an axial movement of the locking member 24 relative to the slideway 210 while avoiding the rotation of the locking member 24 relative to the slideway 210. For example, a surface of the locking member 24 in contact with the slideway 210 can be configured to be a non-circular surface (for example, a rectangular surface, or a polygonal surface, or special-shaped surface). Alternatively, the surface of the locking member 24 in contact with the slideway 210 can be configured to be a circular surface having a radial protrusion and a radial recess. In some other embodiments, the rotation of the locking member 24 may not be limited by the slideway 210, as long as the locking member 24 at the locked position can lock the pivoting arm 22 in a pivot position.

In some embodiments, the switching of the locking member 24 between the locked position and the unlocked position can be achieved by a user to push a load bearing end 24 a of the locking member 24, so as to move the locking member 24 in an axial direction parallel to the axis X-X of the first pin shaft 23. In some embodiments, the support connecting structure 200 may further include an elastic restoring element 25. The elastic restoring element 25 is configured to keep the locking member 24 at the locked position. Subjected to an external force, the locking member 24 is capable of overcoming a force of the elastic restoring element 25 and moving to the unlocked position. As such, the locking member 24 is kept at the locked position in a normal state, such that the stability of the locking member 24 at the locked position is maintained. When the locking member 24 is required to be switched to the unlocked position, only an axial force is required to be applied to the locking member 24. The elastic restoring element 25 may be, for example, a spring sleeved on the locking member 24. When the locking member 24 is pushed by the external force to move to the unlocked position, the spring is stretched or compressed. When the external force is removed, the spring can immediately drive the locking member 24 to automatically return to the locked position and can keep the locking member 24 at the locked position.

In some embodiments, an axial limiting structure configured to prevent the locking member 24 from accidentally disengaging from the slideway 210 may be further disposed on the pivoting base 21. The axial limiting structure may be designed in any appropriate manner. Some embodiments of the axial limiting structure are described below.

In addition, in some embodiments, in order to reduce a possibility of unexpected axial movement of the locking member 24 at the locked position to the unlocked position as a result of accidental touch, when the locking member 24 is at the locked position, the load bearing end 24 a of the locking member 24 and the other end 24 b opposite to the load bearing end 24 a do not protrude out of the slideway 210. That is to say, the projections of the load bearing end 24 a and the other end 24 b onto a plane parallel to the axis X-X are within the slideway 210 and between both ends of the slideway 210. In some embodiments, only one of the load bearing end 24 a and the other end 24 b does not protrude out of the slideway 210. It is to be noted that, a situation that an end portion of the locking member 24 slightly protrudes out of the slideway 210 also falls within the protection scope of the present disclosure. In some embodiments, in order to facilitate the application of the external force to the locking member 24, when the locking member 24 is at the locked position, the load bearing end 24 a configured to receive the external force may protrude out of the slideway 210 (as shown in FIG. 4).

Referring to FIG. 1 to FIG. 4, in some embodiments, the first end 221 of the pivoting arm 22 includes a recessed stop 2212, and the locking member 24 includes a protruding stop 2412 a. A surface of the recessed stop 2212 is configured to form the first anti-rotation surface 220. A surface of the protruding stop 2412 a is configured to form the second anti-rotation surface 240. By moving the locking member 24 to the locked position, the recessed stop 2212 and the protruding stop 2412 a are snapped, and the first anti-rotation surface 220 abuts against the second anti-rotation surface 240, such that the pivoting arm 22 can be prevented from rotating. When the locking member 24 is moved to the unlocked position, the recessed stop 2212 and the protruding stop 2412 a are staggered from each other in an axial direction, and the locking member 24 does not limit the rotating of the pivoting arm 22. Therefore, the pivoting arm 22 can rotate about the axis X-X of the first pin shaft 23. In other embodiments, the recessed stop 2212 on the first end of the pivoting arm 22 and the protruding stop 2412 a on the locking member 24 may be interchanged.

Referring to FIG. 3, in some embodiments, the pivoting base 21 may further include arcuate walls 213 concentric with the first pin shafts 23, respectively. A middle portion of the arcuate wall 213 has an overlapping portion 2131 that coincides with the slideway 210. A notch 2132 is formed in the overlapping portion 2131. The first end 221 of the pivoting arm 22 includes an arcuate portion 2211 slidably mated with an inner wall surface 2130 of the arcuate wall 213, and the recessed stop 2212 is located at the middle portion of the arcuate portion 2211. Referring to FIG. 1 and FIG. 3, when the locking member 24 is at the locked position, the protruding stop 2412 a of the locking member 24 is latched in the notch 2132. In this case, the axial position of the locking member 24 is limited. The protruding stop 2412 a extends into the recessed stop 2212 of the first end 221 of the pivoting arm 22 through the notch 2132 and is snapped into the recessed stop 2212, such that the second anti-rotation surface 240 can abut against the first anti-rotation surface 220. As such, the pivoting arm 22 is prevented from rotating in a clockwise direction F1 and in a counterclockwise direction F2 (as shown in FIG. 1). In the above embodiments, by means of the structures such as the arcuate wall 213 and the notch 2132, the protruding stop 2412 a is snapped into the recessed stop 2212 through the notch 2132. As such, not only the structural strength of the pivoting base 21 is guaranteed, but also an overall size of the support connecting structure along the axis X-X can be reduced.

In some embodiments, the first anti-rotation surface 220 may be an inclined surface or a bending surface, and/or the second anti-rotation surface 240 may be an inclined surface or a bending surface. The bending surface may be a right-angled bending surface, a bending surface having a plurality of bends, or any other appropriate bending surfaces, as long as the pivoting arm 22 can be prevented from rotating. It should be understood that, by designing suitable shapes for the notch 2132 and the protruding stop 2412 a, even through the rotation of the locking member is not limited by the slideway 210, the locking member 24 at the locked position can still lock the pivot position of the pivoting arm 22.

Referring to FIG. 3, in some embodiments, the locking member 24 may include a first slider portion 2411 and a second slider portion 2412 that are successively disposed in a sliding direction of the locking member 24 and respectively slidably mated with the slideway 210. The first slider portion 2411 and the second slider portion 2412 can form a slider 241. The slider 241 is, for example, an integrally formed member. The second slider portion 2412 is away from the slideway 210, while the first slider portion 2411 faces the slideway 210. The first slider portion 2411 has an avoiding surface 2411 a. The avoiding surface 2411 a may be slidably mated with the overlapping portion 2131 and can move to the notch 2132. The protruding stop 2412 a is located on the second slider portion 2412. Still referring to FIG. 1, in some embodiments, the second slider portion 2412 may have a substantially rectangular shape. Two adjacent rectangular corners of the second slider portion 2412 form the protruding stops 2412 a, which can be respectively mated with the recessed stops 2212 on the first ends of the two pivoting arms 22. In this case, the first anti-rotation surface 220 and the second anti-rotation surface 240 may be substantially right-angled bending surfaces.

When the locking member 24 is subjected to the external force and overcomes the force of the elastic restoring element 25 to move to the unlocked position, the second slider portion 2412 is moved outward and drives the protruding stop 2412 a to move out of the notch 2132, the second anti-rotation surface 240 is separated from the first anti-rotation surface 220, and the avoiding surface 2411 a of the first slider portion 2411 is slid to the notch 2132 along an outer wall surface of the overlapping portion 2131 and therefore does not intervene in the rotation of the pivoting arm 22. At this time, the pivoting arm 22 can rotate about the first pin shaft 23 to an appropriate position. In the above embodiments, when the locking member 24 is at the locked position, the locking member 24 may come into contact with the slideway 210 by a circumferential surface (including the avoiding surface 2411 a) of the first slider portion 2411 and a partial circumferential surface of the second slider portion 2412, such that there is a relatively large contact area between the locking member 24 and the slideway 210. When the locking member 24 is at the unlocked position, at least the first slider portion 2411 may be maintained to be in contact with the slideway 210. As such, not only the rotation of the pivoting arm 22 is not interfered, but also the first slider portion 2411 can guide the locking member 24 during subsequent movement to the locked position.

Referring to FIG. 1, in some embodiments, an angle limiting structure 2135 is further disposed at an edge of the arcuate wall 213. The angle limiting structure 2135 may be in contact with the first end 221 of the pivoting arm 22 to limit extreme positions of the pivoting arm 22 during rotation in the clockwise direction F1 and in the counterclockwise direction F2. FIG. 1 illustrates the pivoting arm 22 being at one of the limit positions. In this case, the recessed stop 2212 of the pivoting arm 22 is just aligned to the protruding stop 2412 a of the locking member 24. Therefore, the time required by a user to align the recessed stop 2212 to the protruding stop 2412 a can be saved, and the user can easily lock the rotation of the pivoting arm 22 by the locking member 24.

Referring to FIG. 1, in some embodiments, when the locking member 24 is at the locked position, the two pivoting arms 22 are unfolded to be substantially on the same straight line. This corresponds to, for example, a normal use state of a baby carrier. When the locking member 24 is at the unlocked position, the two pivoting arms 22 can be pivoted about the respective first pin shafts 23. When the two pivoting arms 22 rotate to another limit position, the two pivoting arms 22 are folded to be parallel to each other relative to the pivoting base 21. This corresponds to, for example, a folded state of the baby carrier.

Still referring to FIG. 3 and FIG. 4, in some embodiments, the locking member 24 may include a connecting post 242, and a button 243 and the slider 241 are respectively disposed on both ends of the connecting post 242. The button 243 is located at the load bearing end 24 a, and the slider 241 is located at the other end 24 b opposite to the load bearing end 24 a. In some embodiments, the slider 241 may include the first slider portion 2411 and the second slider portion 2412. In other embodiments, the slider 241 may have other configurations. A limiting plate 2101 is disposed in the slideway 210. The limiting plate 2101 divides the slideway 210 into a first slideway portion 211 and a second slideway portion 212, which are located on both sides of the limiting plate 2101, respectively. The button 243 is slidably mated with the first slideway portion 211, and the slider 241 is slidably mated with the second slideway portion 212. A through hole 2102 is formed in the limiting plate 2101 allowing the connecting post 242 to extend through. The limiting plate 2101 can limit axial moving positions of the button 243 and the slider 241, so as to prevent the locking member 24 from disengaging from the slideway 210. That is to say, the limiting plate 2101 forms an axial limiting structure to prevent the locking member 24 from disengaging from the slideway 210. In other embodiments, the axial limiting structure may include, for example, some steps formed at different positions of the slideway 210. The steps can limit moving positions of the button 243 and the slider 241, so as to prevent the locking member 24 from disengaging.

FIG. 4 illustrates the locking member 24 being at the locked position. The elastic restoring element 25 is a spring mounted in the first slideway portion 211 and located between the limiting plate 2101 and the button 243. In this embodiment, when the button 243 is pressed by the external force, the locking member 24 moves leftward in a direction indicated by an arrow L in FIG. 4 towards the unlocked position in the axial direction (substantially same as the extending direction of the slideway 210), and the spring is compressed. When the external force is removed, the locking member 24 moves rightward in a direction indicated by an arrow R in FIG. 4. The spring tends to drive the locking member 24 to move to the locked position in the axial direction. In other embodiments, the elastic restoring element 25 may include a spring mounted in the second slideway portion 212 and located between the limiting plate 2101 and the slider 241. For example, both ends of the spring are connected to the limiting plate 2101 and the slider 241, respectively. When the button 243 is pressed by the external force, the locking member 24 moves to the unlocked position and the spring is stretched. When the external force is removed, the spring tends to drive the locking member 24 to move to the locked position in the axial direction.

In some embodiments, the button 243 and the connecting post 242 may be integrally formed, for example, by injection molding. The slider 241 may be connected to the connecting post 242 by a fastener 26 (as shown in FIG. 4). In some embodiments, the fastener 26 is, for example, a bolt. The bolt extends through a through hole of the slider 241 and is threadedly engaged in a center hole of the slider 241.

Still referring to FIG. 3 and FIG. 4, in some embodiments, the pivoting base 21 may further include a sleeve portion 214. The sleeve portion 214, for example, extends from the arcuate wall 213 in a direction away from the first end 221 of the pivoting arm 22. A hook 2413 is disposed on the locking member 24. For example, the hook 2413 is disposed on the slider 241. The support connecting structure 200 further includes a fixing arm 27. A first end of the fixing arm 27 has a snap opening 270. The first end of the fixing arm 27 may be inserted into the sleeve portion 214. When the locking member 24 is at the locked position, the hook 2413 can extend into the sleeve portion 214 through an opening 2140 of the sleeve portion 214 and can be snapped into the snap opening 270, such that the fixing arm 27 is connected to the pivoting base 21. When the locking member 24 is at the unlocked position, the hook 2413 can escape from the snap opening 270, thus allowing the fixing arm 27 to be disengaged from the sleeve portion 214. As such, locking of the pivot position of the pivoting arm 22 relative to the pivoting base 21 and the detachable connection between the fixing arm 27 and the pivoting base 21 are associated by the same locking member 24. Therefore, the support connecting structure 200 having a simple structure and easy to fold and disassemble is provided. In some embodiments, for example, a limiting step is formed in the sleeve portion 214. The limiting step can, for example, abut against the first end of the fixing arm 27 to limit an insertion depth of the fixing arm 27 in the sleeve portion 214. When the hook 2413 is snapped into the snap opening 270, the limiting step can limit the fixing arm 27 from moving in a direction out of the sleeve portion 214.

In some embodiments, the hook 2413 includes a U-shaped plate 2413 a, and a pair of hook-shaped portions 2413 b connected to the U-shaped plate 2413 a. The pair of hook-shaped portions 2413 b can be snapped into the snap opening 270, simultaneously. The second slider portion 2412 of the slider 241 may include a groove 2410 configured to partially accommodate the U-shaped plate 2413 a. The U-shaped plate 2413 a may be, for example, detachably mounted in the groove 2410 by the fastener 26. Since the hook 2413, which is a vulnerable part, is detachably connected to the slider 241, the user can maintain and replace the hook 2413 conveniently. In some embodiments, the slider 241 may further include a separation portion 2401 extending between both opposite sidewalls of the U-shaped plate 2413 a, thus improving the structural strength of the hook 2413.

FIG. 5 to FIG. 7 show a perspective view of a crib body 100 of a baby crib according to some embodiments. The crib body 100 employs the support connecting structure 200 according to the above embodiments.

The crib body 100 may include an upper crib fence 10 a and a lower crib fence 10 b located under the upper crib fence 10 a. The upper crib fence 10 a and the lower crib fence 10 b both have a substantially rectangular shape.
